AUTOMOBILE RADIATOR.

Application filed June 13, 1921.

To all whom it may concern:

Be it known that we, CLINTON COSTELLOE and SHERM G. STOLL, citizens of the United 1 States, and residents of Hammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Automobile Radiators, of which the following is a specification. v Our invention relates to improvements in automobile radiators, more particularly of the radiator disclosed in our Patent 1,343,352, granted June 15, 1920, and it consists in the construction, combinations and mode of assembly herein described and claimed.

One of the foremost objects of the invention is to provide a novel and simple arrangement for tightly fitting the ends of the radiator tubesinto an end casting to pre vent the leakage of water.

A further object of the invention is to as readily withdraw the ends of the tubes from the casting by reversing the operation of the same arrangement.

Other objects and advantages will appear in the following specification, reference being had to the accompanying drawings, in which: 7

Figure 3 is a detail sectional view similar to Figure 2, showing the sealing plates as havingmoved the radiator tube to the sealed position, 7

Figure 4 is a horizontal section on the line 4-4 of Figure 2,

Figure 5 is a plan view of the upper sealing plate, the radiator tubes being shown in section,

Figure 6 is a plan view of the lower sealing plate,

igure 7 is a detail sectional view il1ustrating how the lower sealing plate is positioned to abstract the tube from the sealing position, and 1 v Figure 8 is a detail front elevation of the improved radiator, illustrating a slight modification in the form of the sealing plates and also showing radiating fins or plates Serial No. 477.137.

which may be used in connection with the tubes.

In producing our improved radiator, we provide a plurality of radiator tubes 1 with frusto-conical ferrules 2 on the ends, for the purpose of entering the tapering recesses 3 and abutting the shoulders 4 of the top casting 5 (for example) and producing an absolutely fluid-tight and smooth-bored passage. The ferrule 2 (referring now to only one of the tubes 1) includes the enlarged body 6 with upper and lower circular flanges 7 and 8.

It is more particularly the purpose of the present invention to provide means for forcing the ferrule ends of the tubes 1 into the recesses 3 and thus produce and maintain the fluid-tight joint spoken of. The upper and lower sealing plates 9 and 10 are the direct instruments by which this is accomplished. The respective plates have transverse series of pyramidal ridges 11 and 12, the apices of which approximately come in line with transverse rows of the tubes 1.

The radiator tubes 1 are staggered in arrangement as can be plainly seen in Figure 5. This enables getting the tubes closer together. The pyramidal ridges occupy the valleys of the respective plates 9 and 10, so that upon movement of the bottom plate 10 to the right (considering that plate as being capable of moving in a horizontal plane only) there will be an upward or vertical movement of the upper plate 9, resulting in the raising of the ferrules 2 and tubes 1, by virtue of the engagement of the right sides of the pyramids 12 with the left sides of the pyramids 11.

This right movement of the bottom sealing plate 10 is produced by screwing the nut 13 down on the bolt 14 which projects from the flange 15 of the sealing plate through the vertical slot 16 in the end bridge 17. The left end of the sealing plate is unsupported, that is to say by means equivalent to the bolt 14, but is kept from drooping by lateral angle plates 18, shown in connection with the modified construction of sealing plates in Figure 8.

A bolt 19, projecting through a slot 20 from a flange 21 at the left end of the upper sealing plate 9 is for a purpose similar to that of the bolt and nut 14.13, although the bolt 19 is for the purpose of abstracting the ferrules 2 from rather than forcing them into the recesses 3. The slot 20, vertical like the slot 16, is formed in the left end bridge 22, similar to the right end bridge 17 mentioned before. The bridges are secured be tween top and bottom castings of the radiator of which the top casting 5 only is illustrated. The end bridges are divided as shown in Figure 1, the upper portion having an inwardly bent tongue 22 with a slot 22 through which, and an opening in the lowermost section, one or more bolts 22 are fastened to enable longitudinal adjustment of the end bridges when the plates 9 and 10 at the top and bottom are operated to seat the ferrules 2 in the conical recesses 3. Recourse may be had to our patent. mentioned above or our co-pending application #2, for detailed illustration of the whole radiator structure.

There is a neutral and an operative position of the sealing plates 910. When in the neutral positions as in Figures 1, 2 and 5, the larger ones 23 of the vary-sized openings in the plate 9 coincide with the flanges 78 of the enlarged bodies 6. Similarly, the enlarged portions 24 of vary-sized openings 'in the bottom plate 10, coincide with the flanges 7-8 of the bodies 6, but as shown in Figure 6, the enlarged openings 24 are a little longer. than the openings 23 in the upper plate, this for the purpose of accommodating the right movement of the plate 10 when the sealing operation is begun. The obvious purpose of providing this coincident arrangement of the sealing plates is, to enable moving the tubes up and down to properly seat the ferrules 2 in the re cesses 3.

It is necessary to first move the upper plate 9 toward the left in order to get the plate. The necessary left movement of the smaller portion 25 ofthe openings in the plate around the bodies 6 of the ferrules beneath the upper flanges 7. These flanges thus engage the upper surface of the top top plate is gotten by screwing the bolt 19 toward the right. The part that would correspond to the nut of the bolt is brazed or ogherwise ailixed to the flange 21 of the top p ate.

Assuming the smaller openings 25 of the top plate to be seated around the bodies 6 as in Figure 3, the nut 13 of the bolt 1-1 at the right is next manipulated so as to convey the bottom sealing plate 10 toward the right, causing the right side of the pyramidal ridges to ride against the left side of corresponding ridges on the top plate, thereby causing the upward movement of the top plate until a position of all of the ferrules 2, corresponding to that of the ferrules 2 in Figure 3, is reached. Any tendency toward component downward movement of the plate 10 is resisted by the angle plates upon which it rides.

In abstracting the ferrules from the conical recesses, the reverse operation takes place. The sealing plates are moved high enough to enable setting the smaller portions 26 of the vary-sized openings in the bottom sealing plate 10, around the, enlarged bodies 6 but above the bottom flanges 8, as shown in Figure 7. The bolt 19 of the upper sealing plate 9, now becomes the instrument for forcing the bottom sealing plate down, and this is accomplished by turning the bolt so as to convey the upper sealing plate toward the left. When this is done, the left sides of the pyramidal ridges 11 bear against the right sides of corresponding ridges 12 on the lower sealing plate, thus producing a downward movement of the latter plate and the consequent removal of the ferrules from the recesses 3. When the sealing plates are raised into the position in Figure 7, the upper end of the slot 20 prevents the rising of the upper sealing plate 9 when the bolt 19 is turned, and thus that plate is set in a substantially horizontal position from which it is immovable when pressing the lower sealing plate down. In the modification in Figure 8, the upper and lower sealing plates 9 and 10 are for a purpose identical with that of the sealing plates 9-10 for example in Figure2. The only difference is one of construction, and in the modification, instead of the companion faces of the sealing plates being formed in traverse pyramidal ridges, they are provided with transverse ridges 11-12 of a saw-toothed shape in cross section. Bolts 14: and 19*, respectively at the right and left of the radiator, are for the same purposes as before, namely, to move either one of the sealing plates for forcing the ferrules in or abstracting them from the recesses. V
